Question

In this equation, what is y when you substitute in -5 for x? y = -2x - 16 *

Answer 1

Given the equation :

`y=-2x-16`

We need to find the value of y when x = -5

so,

Substitute with x = -5

so,

`\begin{gathered} y=-2\cdot-5-16 \\ \\ y=10-16 \\ \\ y=-6 \end{gathered}`

So, the value of y = -6
